Frequency band selection

Abstract

Frequency band selection for tuning an antenna are disclosed. In one example, one of a Received Signal Strength Indicator (RSSI) value and an echo value of a plurality of frequency bands is obtained. Based on one of the RSSI values or the echo values of the frequency bands, a frequency band is selected. The selected frequency band is transmitted to a tuning component to tune the antenna of the electronic device.

         3 . The system as claimed in  claim 1 , wherein the processing unit is to select the frequency band based on a region code, when one of the RSSI value and the echo value is below a first threshold value. 
     
     
         4 . The system as claimed in  claim 1  further comprises a receiver unit coupled to the processing unit, to,
 communicate with the antenna to receive the plurality of frequency bands; and 
 measure at least one of the RSSI value and the echo value of each of the plurality of frequency bands. 
 
     
     
         5 . The system as claimed in  claim 4 , wherein the processing unit is to,
 monitor one of the RSSI value and the echo value of the selected frequency band; and   when one of the RSSI value and the echo value of the selected frequency band goes below a second threshold value, send a notification to the receiver unit to share one of a current RSSI value and a current echo value pertaining to each of the plurality of frequency bands.   
     
     
         6 . The system as claimed in  claim 5 , wherein one of the RSSI value and the echo value of the selected frequency band is monitored continuously, periodically, and at a specified time interval. 
     
     
         7 . The system as claimed in  claim 1  further comprises a control unit, coupled to the processing unit, to
 receive, from the processing unit, instructions indicating the selected frequency band to be used as the frequency band by the tuning component; and 
 forward the instructions to the tuning component. 
 
     
     
         8 . A method for selecting a frequency band for tuning an antenna of an electronic device, the method comprising:
 measuring, by a receiver unit, a Received Signal Strength Indicator (RSSI) value and an echo value pertaining to each of a plurality of frequency bands;   based on the measuring, selecting, by a processing unit, a frequency band having one of the RSSI value and the echo value above a first threshold value, wherein the selecting comprises;
 monitoring one of the RSSI value and the echo value of the selected frequency band; and 
 selecting another frequency band when one of the RSSI value and the echo value of the selected frequency band goes below a second threshold value. 
   
     
     
         9 . The method as claimed in  claim 8  further comprising transmitting, by the processing unit, the selected frequency band to a tuning component for tuning the antenna based on the selected frequency band. 
     
     
         10 . The method as claimed in  claim 8 , wherein the selecting comprises receiving, from the receiver unit, one of a current RSSI value and a current echo value pertaining to each of the plurality of frequency bands, when one of the RSSI value and the echo value of the selected frequency band goes below the second threshold value. 
     
     
         11 . The method as claimed in  claim 8 , wherein the selecting comprises obtaining a frequency band based on a region code of the electronic device, when one of the RSSI value and the echo value goes below the first threshold value. 
     
     
         12 . The method as claimed in  claim 8 , wherein the transmitting comprising:
 converting a digital signal containing information pertaining to the selected frequency band, into an analog signal; and   providing the analog signal to the tuning component to tune the antenna.   
     
     
         13 . A non-transitory computer-readable medium having a set of computer readable instructions that, when executed, cause a processing unit to,
 receive values pertaining to one of a Received Signal Strength Indicator (RSSI) and an echo for each of the plurality of frequency bands;   select a frequency band based on one of the measured values and a region code, wherein when any of the measured values is below a first threshold value, a frequency band based on the region code is selected;   transmit a digital signal containing the selected frequency band to tune an antenna, wherein the digital signal is converted into an analog signal and provided to a tuning component to tune the antenna based on the selected frequency band.   
     
     
         14 . The non-transitory computer-readable medium as claimed in  claim 13 , wherein the computer readable instructions, when executed, further cause the processing unit to,
 monitor one of the RSSI value and the echo value of the selected frequency band; and   send a notification to the receiver unit to share one a current RSSI value and the echo value pertaining to each of the plurality of frequency bands, when one of the RSSI value and the echo value of the selected frequency band goes below a second threshold value.   
     
     
         15 . The non-transitory computer-readable medium as claimed in  claim 14 , wherein the computer readable instructions, when executed, further cause the processing unit to select another frequency band for tuning the antenna, when one of the RSSI value and the echo value of the selected frequency band goes below the second threshold value.
